I seem to have developed an allergic reaction to dry peppers, so crumbling dry peppers with my bare hands is not a good idea. I see a few options:
(a) use surgical gloves -- a hassle, and a waste of gloves unless I manage to re-use them. Plus the flakes stick to them.
(b) Put the pepper inside a small plastic bag and crumble from outside. (This sort of works, but not great).
(c) Pestle and mortar -- didn't work well for me in a Le Creuset stoneware one, maybe I do not have the right pestle.
(c) Give up on dried peppers :-)
Any other idea? Many thanks! -- CF
